Forage Under Sprayed Trees
Categories: Fruit Growing
Is it safe to use arsenical sprays in a pear orchard in which alfalfa is
raised between the trees and afterward cut and fed to cattle?
It was fully demonstrated by experiment about 25 years ago that herbage
under trees sprayed with paris green at the rate of 1 pound to 160
gallons of water was not injurious to animals pasturing upon it. We are
not aware that such an experiment has been made with the more recently
used arsenates - which can be used with a much higher amount of arsenic
to the gallon because they do not injure the foliage - to determine
whether the herbage below would be poisonous or not. Presumably not,
because modern spraying does not admit as much loss from run-off as was
the case with old Spraying methods.
